Togall whom it may concern Be it' known that I, HOWARD F. MAXIM, a citizen of the United States, residing at Loclre Mills,in the county of Oxford and State of'Mai-ne, have invented certain new and useful Improvements in Railway-Ties,

"of which the following is a specification.

- This invention relates to railway ties, and 5 more especially to thosemadeof metal; and

the object of the same is to producek a twopart tie including a base and a top plate, with mechanical means for adjusting the latter upon the former so as to straighten out the line of railway being built or to true a curve therein.

This Object is accomplished b the means set forth in the following specilication, and reference is made to the drawings, wherem:-

Figure 1 is a side elevation of one of my improvedties,

F'g. 2 a plan view partly in section,

and

Figs. 4: and 5 sectional details on the lines 4-4 and 55 respectively. of Fig. 2;

-The base 1 of this improved tie may be made of malleable casting, of sheet metal,

and of a single part or of a plurality of parts as desired; and its details of construction-are not important further than that itshould have a flat top as indicated at 2, and preferabl a flat bottom 3 which rests upon the road ed, and preferably it is composed of a central longitudinal upright web 4 connecting the top and bottom as best seen in Fig. 4, the same being provided with a number of transverse upright webs 5 so that the ballast of the road bed may be filled in and tamped around said webs to'hold the base securely in position. Its dimensions, proportions, and details are otherwise unimportant excepting as hereinafter stated.

1 Overlying this bed is a top plate broadly indicated by the numeral 10 preferably made of two substantially rectangular heads 11 connected by a narrow shank 12, and

each head has a transverse channel 13 of a size and shape to receive the base of a rail 14. Through the head at both sides of the channel are formed upright holes as indicated at 15, for the passage. of bolts 16 whose headswhen in-place overlie the base of the whoseshanks pass down through these holes and receive nuts at their lower ends. Thus the top plate will hold the two rails equally spaced at all times, and the.

spacing of course will correspond with the gage of the road being built. In-the the base and at opposite sides of its longitudinal web 4 are formed longitudinal slots 25 coincident with the holes 15, and through whose centers the bolts 16 will extend when the parts are disposed in their normal position; and the nuts 26 of the bolts will underp of I" lie the top flange of the base as best seen In the upper face of-said basebetween the pairs of slots 25 is disposed a groove or channel 20 enlarged at its inner endinto .a

recess 21 as best seen in Figs. 3 and 5, the

them when the top plate 10 is removed. flhe channel or groove 20, its outer end projectside walls of said recess having notches Q2 I at its inner end for the reception of an ai'p- 1 rlght plate 23 which may be dropped into I numeral 27 designates a shaft lying in said Fig. 3 a plan view of one end of the base,

ing beyond the base and squared or otherwise made angular as at 28 for the reception of a wrench or key, and its inner and threaded as at 29 for the; reception of a nut 30 which is of a size to move freely within the recess 21' as will be clearly understood. The inner extremity of this shaft is journaled in the plate 23 so that it may rotate therein and in the channel Without movin longitudinally in the base of the tie, an such rotation is obviously accomplished by turning the shaft by its angular outer end 28. The nut 30 rises above the upper face of the base of the tie, and enters a cavity 31in the lower face of the top plate 10 as seen only in Fig. 5, and therefore adjustment of the shaft and longitudinal movement of the nut within the recess cause a corresponding upon the base 1 as well be clear.

longitudinal movement of the top plate 10 With this improved tie it is possible after the same has been set in -the"road bed and leveled if the track is straight or given the proper pitch if the track is curved at this point, for the track layers to come later and apply the top plate and then the rails, putting in the bolts 16 and applying their nuts 26 rather loosely to hold all parts assembled and finally the rails are trued by adr.

its

justment of the shaft with akey,{'appl1ed, at ll its outer end as already suggested, and then- I the aints 26.5011 the lower ends of the bolts 16 are setup tight to hold the tppplate and all parts in their adjusted positions.

What is claimed as new is:'

1. A railway tie comprising a base consisting of a top, a bottom, an upright web connecting them, and transverse webs also connecting said top and bottom,- the top having pairs of longitudinal slots near each end on opposite sides of the longltudlnal web;

' and a top plate overlying said base and provided with rail-channels across its upper face nearflits ends and with upright boltholes at opposite sides of each channel adapted to come opposite the slots in the base.

2. In a railway tie, the combination with a skeleton baseehaving a flat to and near each end of the same two pairs 0 longitudinal slots; of a top plate overlying said top and having near each end a transverse railchannel with upright bolt-holes on opposite sides thereof adapted to register with said slots, and bolts engaging said holes and slots. I 3. In a railway tie, the combination with a skeleton base having a flat top and near each end of the same two-pairs of longitudinal siots; of a top'plate overlying said top and, having near each end a transverse railchannel withupright bolt-holes on opposite sides thereof adapted to register with said slots, bolts engaging said holes and slots, and

mechanical means for adjustin .the top plate longitudinally on the base fore the nuts on the bolts are set up.

4. In a railway tie, the combination with aslteleton base having a fiat top and near each end of the same two pairs of longitudithe 5} In a railway tie, the combination. with askeleton base having a fiat to and near each end of the same two pairs 0 'lougzmi nal slots; ofa top plate overlying said top and havin near each end a transverse ra lchannel with-upright bolt-holes on opposite sides thereof adapted to register with said slots, bolts engaging said holes and slots, the top of said base near one end being provided with a longitudinal channel enlarged at its inner end into a recess, a longitudinal shaft rotatably mounted in said channel and having its inner end threaded with said recess and its inner extremity rotatablv connected with the base and its outer end squared, and a nut engaging said threaded portion and slidable within the recess, the upper portion of.the nut engaging said top plate, for the purpose set forth.

6. In a railway tie, the combination with a'base having a flat top and in one end of the latter a longitudinal channel enlarged at its inner extremity into a recess, a shaft rotatably mounted in said channel and having its inner extremity threaded within said recess, and a nut engaging said threaded extreinity and movable Within the recess; of atop plate overlying the base and having a cavity in its under face removahly engaging'the nut, means on its upper face for'the attachment of rails thereto, and means ior fastening the top plate to the base after the adjustment of the former.

7. In a railway tie, the combination with a base having a fiat upper face and at each end thereof a longitudinal channel, a recess at the inner end of the latter andtside notches at the inner extremities of the-re cess; of a shaft rotatably mounted iiitsaid channel, threaded at its inner portion within said recess and squared at its outer end, a plate engaging said notches and within which the inner extremity of the shaft is journaled, a nut mounted on said threaded portion and movablem said recess, a ra1l-,

carrying plate overlying said base and having a cavity with which said nut removably engages, and means for fastening said plate to the base after adjustment. V

In testimony whereof I afiix my signature inpresence of two witnesses.
